Kentico allows you to extend the scope of available features. You can achieve this by integrating applications, utilities, website templates, etc. developed outside Kentico by third parties. You can also enhance the system by adding your custom [applications](https://docs.kentico.com/k81/e-commerce-features/customizing-and-developing-your-store.md), [web parts](https://docs.kentico.com/k81/custom-development/developing-web-parts.md) and other items.

## Integrating your custom functionality

- You can integrate features that you developed according to your specific requirements.\
  For example, you can add your custom applications, templates, web parts, etc. You can also create your custom payment gateways, as described in detail in [Creating a custom payment gateway](https://docs.kentico.com/k81/e-commerce-features/customizing-and-developing-your-store/e-commerce-customization-examples/creating-a-custom-payment-gateway.md).
- You can integrate other third party functionality.\
  The system allows you to add third party features using, for example, the built-in [integration bus](https://docs.kentico.com/k81/integrating-3rd-party-systems/using-the-integration-bus.md) or [REST service](https://docs.kentico.com/k81/integrating-3rd-party-systems/kentico-rest-service.md).

If you need to customize the behavior of the system or wish to personalize its built-in applications, see [E-commerce customization model](https://docs.kentico.com/k81/e-commerce-features/customizing-and-developing-your-store/e-commerce-customization-model.md).
